Should local officials actively manage coyote populations in residential neighborhoods to ensure community safety?
University of Washington researchers found that Seattle coyote populations are nine times denser than in rural parts of the state. The study identified 261 individual coyotes through DNA analysis of scat samples collected across the city.
Why it matters
Urban environments in Seattle provide coyotes with abundant food and fewer natural predators, causing them to thrive in metropolitan settings compared to wild study areas like Winthrop and Chewelah.
Researchers analyzed 842 scat samples to identify 261 distinct coyotes. This density is significantly higher than that found in natural Washington study sites and follows a broader trend seen in cities like Los Angeles, where densities are seven times higher than in the wild.
The players
University of Washington
A major research institution that monitors local ecological shifts and wildlife behavior.
Environmental Research: Ecology
A scientific journal that publishes peer-reviewed research on environmental systems.
The details
Researchers determined population density by mapping scat DNA against variables including tree cover, pollution, and local income levels. Urban coyotes have adapted to city life by eating a diet twice as diverse as their rural counterparts. While these animals thrive on abundant urban food sources like rabbits, they primarily face mortality risks from vehicle collisions and disease.
Timeline
Over the past century, coyotes have colonized every major metropolitan area in North America.
A rabbit population boom in the past few decades has shifted urban ecology in Seattle.

The Home Front
Coyotes have successfully colonized every major metropolitan area in North America over the past century. This study illustrates how urban development patterns have created specific ecological niches that support higher predator densities than previously observed.
Homeowners should be aware that urban environments, including those with higher rabbit populations, draw coyotes into residential areas. Ensure that garbage containers are securely latched and keep small pets supervised when outdoors.
The takeaway
Urban coyotes have evolved to rely on a diverse diet and face fewer threats from predators, leading to higher local populations. Residents can track local activity by keeping an eye on yard waste and securing food sources to minimize interactions.
